4 Claims.

This invention relates to heavy, extruded, rigid, metal bars adapted for joining the adjacent edges of sheet glass store and window fronts at different angles, as distinguished from those window or store front bars which are of wood, covered with light sheet metal or which depend upon special clamps or fastenings to effect rigidity of connection.

The object of the invention is the provision of an improved combination or universal corner, reverse or division bar wherein the face and back pieces are of heavy extruded metal adapted to be used with, or without, a re-inforcing channel piece of any desired shape or contour and which may be adapted for the setting of the panes which are joined by the bar so that they will be disposed in relation to each other at an angle of from to 180.

Another object is to provide in a bar of the character specified, front and back pieces having improved rounded contact parts which directly contact with or engage opposite sides of the pane, in each instance, and prevent breakage of the panes, due to binding and thus overcome the defects inhering in front and back pieces having flat or sharp contact biting surfaces engaging the pane, as heretofore proposed. I have found that flat contact or biting surfaces of from one fourth to one half inch in width have a tendency to fracture the pane and this is also true of those bars which have sharp, straight edge contact or biting surfaces. My presentimproved smooth rounded rocker contact surfaces on the front and back pieces entirely eliminate danger of breakage.

A further improvement resides in providing both the front and back pieces of the present invention with channels in their inner faces, said channels being so related to the rounded rocker contact faces that the edges of the pane cannot come in contact with the metal when the glass rocks or vibrates, and hence I thereby prevent fracture from that cause. These channels also permit the panes to be set at an angle of from 90 to 180 and then to be clamped by direct engagement with the smooth rounded contact faces in the front and back pi ces and held in their set position by tightening the screws employed for that purpose without danger of the panes engaging the front and back pieces except where clamped by the rounded contact faces.

A further object is to provide a back piece having an exterior or rear face of improved contour adapting it to be engaged by a channel strip in such manner that the channel strip is held against displacement when engaged by the connecting screws and assists in aligning the front and back pieces when engaged with the panes and also distributes the straining pressure exerted by the screws along the length of the front and back pieces.

I have described hereinafter certain embodiments of the present invention to illustrate its uses as a universal bar for holding the panes of store fronts and windows but it is to be understood that the invention may be employed in variants of the constructions hereinafter described, if contemplated by the essential principles involved in the use of the smooth rounded pane-engaging surfaces on the front and back pieces, and the clearance channels which are provided on said pieces, as well as the construction for engaging the channel piece.

Fig. 14 is a diagrammatic View illustrating the various angles at which a pane may be set, more particularly in connection with the universal or combination bar of Fig. 1 but also, to a certain extent, in connection with the bars shown in Figs. 4 and 8.

Referring first to the construction shown in Figs. 1, 2 and 3, this is adapted for use as a corner bar, a reverse bar,'or a division bar. As shown in full lines, the panes 1 and 2 are held at an angle of 90, such as would be the case if the corner of the store front is a right angular one. The lowermost dot and dash lines illustrate how this form of invention may be used as a division bar where the panes are in the same plane, that is, arranged at an angle of 180' in relation to each other. The upper dot and dash lines show the panes at an angle of nearly 180. The bar illustrated in Fig. 1 is universal because it is adapted to serve in connection with panes disposed at any angle between 90 and 180, inclusive. The bar shown in Figs. 1, 2 and 3 comprises an outer or front piece 3, an inner or back piece 4 and, if desired, a channel piece 5 connected together by a screw 6 which engages an internally screw threaded sleeve nut 7.

The outer or front piece 3 is of bowed shape having a hole 8 through which passes the screw 6, there being a nut 9 on said screw to rigidly clamp it to the front piece 3.

The rear or back piece 4 has a hole 10 through which passes the screw 6, said screw having a clamping nut 11 bearing on the inner face of said back piece 4. The screw is engaged with the sleeve nut '7 which has a head bearing against the inner face of the channel piece 5, said channel piece bearing on the back piece 4 in a manner which will presently be described.

The outer or front piece 3 is provided at its longitudinal inner edges with smooth rounded bearing faces 12 which are, in effect, longitudinal beads extending the full length of the front piece 3. These beads or smooth rounded contact surfaces are adapted to directly bear on the outer surfaces of the panes 1, 2.

The outer or front piece 3 is provided with longitudinally extending recesses or channels 13 running from end to end of the said piece. The purpose of the channels 13 is to provide clearance spaces which prevent any contact of the piece 3 on the panes 1, 2 except at the rounded bearing or contact surfaces or pieces 12, regardless of the angle at which the panes are set in relation to each other.

Due to the foregoing construction, it will be seen that the outer piece 3 has only a rocker bearing on the panes and consequently the pane can rock or vibrate under wind pressure or from any other cause without danger of breakage. In that connection, the channels or recesses 13 have utility in connection with the bearing surfaces 12 because the pane cannot be cramped when rocking or vibrating. Furthermore, the

- rounded surfaces or beads 12 and the recesses 13 prevent any breakage of the panes when the bar and panes are being connected and the screws 6 are being tightened.

My improvements in the foregoing respects have great practical advantages over corner, reverse, or division bars which have flat or sharp surfaces bearing on the panes.

, The front and rear pieces, 3, 4, are of heavy, extruded metal which affords the requisite strength and rigidity and entirely do away with re-inforcements, thus being distinguished over former constructions employing thin sheet metal backed with reinforcements.

It is preferable to employ a rigid channel bar 5 to equalize the strain, such bar being connected to the front and rear pieces 3, 4 by the screws 6 and nuts 7, which connect said bar to the pieces 3 and 4 at intervals of the length of said pieces and bar. The bar 5 preferably extends the full length of the pieces 3 and 4.

The back piece 4 is provided with smooth rounded contact surfaces 14 in the form of beads extending the full length thereof. These surfaces 14 bear directly against the inner surfaces of the panes l and 2 at points which are relatively opposite to the contact surfaces or beads 12.

The panes 1, 2 being held between opposing rounded and smooth contact surfaces 12, 14, the rocking action previously explained, may take place without any possibility of chipping or breakage of the panes 1 and 2 and these contact surfaces 12, 14 afford the proper bite on the panes regardless of the angle at which the panes are set.

The back piece 4 is provided with longitudinally extending abutments 15 which, as shown in Fig. 1, are in the form of ridges, the channel bar 5 being provided with longitudinally extending and inturned feet or flanges 16 which bear on the ridges 15, said flanges and ridges resisting expansion of the walls of the channel bar 5 under the compressive strain, due to the tension of the screw 6 and also centering the channel 5 in relation to the piece 4, thus adding to the rigidity of the construction.

Referring to Figs. 4, 5, 6, 7, while the shape of the front and rear pieces 3, 4 is slightly different from that illustrated in Figs. 1, 2, 3, the principle involved is the same, there being employed the same smooth, rounded bearing surfaces or beads 12, 14, the same screw 6, nut 7, and channel piece 5, as well as the clamping nuts 9 and 11. Instead of ridges 15 being provided on the back piece 4, grooves 17 receive the flanges 16 but it will be observed that the flanges 16 bear against the walls of the groove and effect the same purpose as in the construction shown in Fig. 1.

The construction shown in Fig. 4 is particularly adapted for use as a corner bar for angles of from 90 to 125.

In the embodiment illustrated in Figs. 8, 9 and 10, all of the parts present in Figs. 1 and 2 are included in any slightly different form. The flanges 16 of the channel bar 5 are received in grooves 18 of slightly different shape from the groove 17, there being abutting channels or ridges on the back piece 4 with which the flanges engage.

The range of angular adjustment is less in the construction shown in Fig. 8 than that shown in Fig. 4.

Referring to Figs. 11, 12 and 13, an embodiment of the invention representing a division bar is therein shown. There are duplicate front and rear pieces 3, 4 which are flat and whose smooth curved contact surfaces or beads 12, 14 respectively engage opposite sides of the panes 1, 2. The flanges 16 of the channel bar 5 bear against the piece 4 in substantially the manner shown in the form illustrated in Fig. 8.

Fig. 14 illustrates in a diagrammatic manner by full and dotted lines, the various angular positions which the panes may assume without interfering with the clearance spaces 13, 13' and also the adaptability for rocking of the panes.

What I claim is:

1. A combination or universal corner, reverse, and division window or store front bar provided with continuous, rounded bead-like contact parts e x tending lengthwise thereof constituting the sole means thereon to bear directly on the panes with which said bar is used, the bar being otherwise out of contact with the panes, said bar having at least its outer strip or section provided with clearance channels extending lengthwise thereof adjacent and disposed inwardly from said rounded bead-like parts and adapted to permit vibration of the panes or desired adjustment thereof to different angles to prevent contact of the panes with the outer section of the bar except at the rounded contact surfaces aforesaid.

2. A window or store front bar comprising inner and outer sections each being provided with rounded contact surfaces at its opposite edges extending in the direction of the length thereof and constituting the sole means thereon to bear directly on the panes with which said bar is used, the bar being otherwise out of contact with the panes, both of said sections having clearance channels extending in the direction of the length of the sections and disposed adjacent and inwardly from the aforesaid rounded contact surfaces, said clearance channels being adapted to receive the free edges of the panes when said panes vibrate and permit adjustment of the panes to different angles without contact with the said sections except at the rounded contact surfaces, said sections being located on opposite sides of the panes in spaced relationship to each other, reinforcing means engaged with the inner section, and

adjustable connecting and tensioning means for securing the said inner and outer sections and the reinforcing means together.
